Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems worldwide that began being recorded at the end of the 20th century. Multiple lines of evidence exist for the reduction of wild pollinator populations at the regional level, especially within Europe and North America.
A foraging pollinator of a species in the Lupinus genus. At the top of the inflorescence are rewarding flowers at anthesis where the spot on the banner petal is yellow. Towards the bottom of the inflorescence there are older purple flowers that are typically avoided by pollinators presumably because they contain less pollen and nectar. [8]
Pollination by a specialist can result in high flowering synchrony, as asynchronous flowering can result in erratic attraction of a specialist to a site. [19] Showy floral displays tend to attract pollinators, [20] [21] and synchronous flowering can attract more pollinators to a population. High pollinator visitation to populations with high ...
Light pollution also plays a role. [7] [8] [9] Other factors that are thought to be important are anthropogenic noise, introduced species, [34] [6] and eutrophication from fertilisers. The use of increased quantities of insecticides and herbicides on crops have affected not only non-target insect species, but also the plants on which they feed.
Bee pollination is important both ecologically and commercially, and the decline in wild bees has increased the value of pollination by commercially managed hives of honey bees. The analysis of 353 wild bee and hoverfly species across Britain from 1980 to 2013 found the insects have been lost from a quarter of the places they inhabited in 1980.
Her main areas of expertise as a social insect biologist are the molecular, physiological, and ecological determinants that affect the health of honey bees and other pollinators. [3] [1] [4] Grozinger has carried out important research into the ways in which bee stressors affect bees, and how factors such as climate change, extreme weather ...

The Wild Kratts learned that two kids' forest clubhouse is dying. They must investigate and solve the tree-killing mystery. At first, Aviva and Koki think that woodpeckers did it but Martin gets trapped in a tree while he's miniaturized and sees a longhorn beetle, a species from China transferred by ships, munching on trees and invading ...
